The '''Excel Spreadsheet (XLS) file format''' has the '''.xls''' extension. This file type originates from [[Microsoft Excel]]. However, other spreadsheet software can be used to display these files as well. These include:
 +
* [[WordPerfect]]
 +
* [[OpenOffice]]
  
This phone is supported by the Cricket Network and Tracfone. This uses a Qualcomm 7627 600 MHz (S1) Processor and comes standard with Android version 2.3. This phone is unsupported by RIFF Box for the JTAG process for resurrector.

The XLS file format should not be confused with [[XLSX]] and [[XSLB]].
